Patented Apr. 29, 1941 UNITED STATES PATENT oFFlcE CARRY BAG I George W. Poppe, Brooklyn, N. Y., assgnor to Equitable Paper Bag Co. Inc., Brooklyn, N. Y., a corporation of NewYork Application October 11, 1939, Serial No. 298,881

2 Claims. Y (Cl. 229-53) 'I'he present invention relates to carry bags having one or more'nger openings in the bag walls, with a tongue or tongues hinged adjacent to said opening or openings, said tongues adapted to lock into a recess in the closing ap.

An object of the invention is the provision of a carry bag which is suiciently strong to support the articles ordinarily placed therein but which may be produced with rapidity on a bag machine and at a. relatively low cost.

A feature of the -lnvention relates to the provision of a bag having offset walls providing a ap at the bottom by which the bag is-closed and a ap at the top which may be folded over to close the mouth of the bag together with locking tongues cooperating with a recess in the flap.

Another feature relates to a bag formed from a bag section, such section having offset walls providing a closing flap at the bottom 'of the section and a closing flap at the top of the section, each flap being a continuation of a respective bag Wall, the closing flap having a recess therein and the opposite end of same wall having a projecting tongue complementary to said recess. When the bag section is folded, the line of fold of the bottom flap encloses within it a portion of the projection thereby reenforcing the bottom; and the complementary recess in theV closing flap adapted to cooperate with locking tongues provided in the bag walls.

` A further feature of the invention relates to a bag having offset walls with a closing ap at the mouth Aof the bag and a closing flap at the bottom of the bag, the closing flap at the bag mouth also having a recess cut from its edge and the same bag wall having a projection comple- .mentary to said recess, said projection extending within the line of the bottom of the bag.

Further features and advantages will become apparent fromthe following description and claims when taken in connection with -thevacfold of the closing flap at Figure 1 is a rear view of the bag'section from which the completed bag is made by folding over the bottom;

' Figure 2 is aview of the front ofthe bag section shown-in Figure 1 but with the closing flap folded over and the locking tongue folded up;

Figure 3 is a section on the-line 3-3 of Figure 1; v

Figure 4 is a view similar to Figure 1 with the central portions broken away and` the bag bottom closed. This type of bag is also providedV with two locking tongues instead of o ne as shown in Figure 1; l

Figure 5'is a section on the line 5-5 of Figure 4; and

Figurei is a top portion of a bag of the Figure 4 construction with the locking flaps folded up.

Referring to the drawing a bag section shown in Figure 1, is made by folding over a web of paper to form a bag tube from which successive bag sections are severed in a manner described in my copending application (case RRJ- Serial No. 298,880 led October 11, 1939. The section then comprises a front wall I, Figure 2 and a rear Wall 2, Figure 1. The folded over web is pasted along a seam line indicated at 3, Figure 1. This seam line may be offset as shown in VFigure 1 or it may be a Wide seam s shown 1n Figure 4. A center seam may also be used, if desired, although since this would somewhat interfere with the locking tongues hereafter to be described, it is preferable to havel either a narrow offset seam or a Wide seam.

The bag section shown in Figure 1 is provided with a bottom flap 4 and a closing flap 6, each ap being a prolongation of a respective bag wall. The top of the wall I is shown in dotted lines at 1, Figure l', and the bottom of the same wall is indicated at 8. The Wall 2, which in the present instance constitutes the seam wall, is provided at its top edge with a rec'e'ss I0 and the opposite end of the same Wall is provided with a projection I2. It is thus apparent that the opposite ends of each bag wall are complementary. This results from the manner in which the bag is made as fully described and shown in my said application (case RRlabove identified.v The side edges of the ap 6 are slightly inclined to the longitudinal axisof thel section and since the bottom is a complement of the top, gussets I4 are formed at either side of the bottom portion of the bag section and by this means a relatively short bottom may be produced by folding the bottom flap 4 along the line a--a,

the-gussets in this case forming reenforcements at the lower corners of the bag. The manner of cutting a bag tube to provide gussets similar to I4 is fully shown and dements set forth 'in the present application, the bag section shown in Figure 13 of said Poppe patent is similar to the vbag section shown in Figure 1 of the present application.

Since this bag is designed as a carry bag, it is desired that it be reenforcedalong its central portion and to this end the projection i2 extends beyond the fold line and is included therein, but the remaining portions of the wall 2 are not included in the fold line.

lln order that the bag mayA act as a locked carry bag, tongues I6 are formed in the bag walls and when the ap 6 is folded over to close the mouth of the bag, as indicated in Figure 2, the tongues i6 are folded up and are locked to'be in cooperation with the edges of the recess I0.

In the construction shown in Figures 4, 5 and 6, two sets of tongues i6 are provided, which, when folded back lock into the recess i0 as shown in Figure 6.

Thus 1 have provided a bag which is formed from a bag section in which a recess l0 is formed in the upper edge ofthe closing ap and a. complementa] projection i2 at the lower end of the bag wall of which the flap 6 is a prolongation. The projection i2 acts as'a reenforcement for the bag bottom having a width, projecting within the fold line, substantially equal toene-third of the bag width. The recess I0 in cooperation with the tongues i6 forms a secure lock after the tongues i6 are folded up and of course the fingers may be passed through the opening in the walls indicated at i8, Figure 2, whereby the bag may conveniently be carried. By reason of the fact that a bag of this type may be made at great rapidity, on a bag machine without any waste of paper, lends to greatly reduced cost ofvproduction. The resulting product is also capable of sustaining greater weights than carry bags of greater cost heretofore produced, dueto the fact that vseparate reenforcing pieces are attached to the bag structure.

at I claim is:

i. A paper bag having front and rear walls. a. bottom ap which is Ia prolongation of the front wall and folded over onto the rear wall to close the bottom of the bag, a top flap which is a prolongation ofthe rear bag wall and foldable over'the mouth of the bag to close the same,

a recess cut from the edge of said closing ap,v a projection at the lower end of the wall of which 2. A paper bag having front and rear walls,y

a bottom iap having gussets at its side, said iiap being a prolongation of one of said front wall and foldable over onto the rear wall to close the bottom of the bag, a top ap which is a prolongation of the rear bag wall and foldable over'the mouth of the bag -to close the same, a recess cut from the edge of said closing flap, a projection at the lower end of the rear wall, said projection being complemental to said recess and having a portion of its width extending across the line of fold of said bottom ap, said bottom ap when folded over to close the bag bottom enclosing said projection within the line of fold but, not the rea'r wall upon which itis folded and locking tongues out from the bag walls adapted to be folded into said recess in the closing ap after the closing flap has been folded over to close the bag mouth.
